Description

Technical Field

[0001] This invention relates to the field of crushing technology, and in particular to a crusher for testing agricultural products. Background Technology

[0002] A crusher for agricultural product testing is a mechanical device that uses physical external forces (such as impact, compression, and grinding) to break large solid materials into smaller pieces, granules, or powder. It is widely used in the mining and agricultural sectors, and its core function is to change the physical form of materials to meet the needs of subsequent processing, transportation, or use. Currently, crushers often leave material residue on the blades and inside the equipment after crushing, which can affect the accuracy of agricultural product testing data. Furthermore, crushers are prone to clogging during screening. Summary of the Invention

[0003] Therefore, it is necessary to provide a crusher for agricultural product testing to solve at least one of the above-mentioned technical problems.

[0004] A crusher for agricultural product testing includes a support assembly, a control assembly, a drive mechanism, a barrier assembly, and a screening assembly.

The cleaning component is rotatably fitted onto the middle of the screening component. Multiple striking components are installed on both the drive assembly and the driven assembly.

[0005] The adjustable parameter control system allows for flexible setting of parameters such as crushing speed, time, and particle size classification to meet the sample processing needs of different testing projects. The drive mechanism's drive and driven components are used to crush objects. The striking component works in conjunction with the blocking component to strike the drive, driven, and protective components, thereby causing the attached object debris and dust to fall off, reducing testing errors. The screening component's screening component can screen the crushed objects with good screening effect and is not prone to clogging. The cleaning component can clean the drive and driven components, causing the attached object debris and dust to fall off, reducing subsequent testing errors.

The crushing protective shell is installed on the top of the support plate, the feeding protective shell is fixedly installed on the top of the crushing protective shell, the discharging protective shell is fixedly installed on the bottom of the crushing protective shell, and the gear protective cover is located at the end of the crushing protective shell away from the energy-saving rotary motor.

[0011] In one embodiment, the blocking assembly includes two blocking bars, which are respectively installed below the rotating shaft and the driven rod, and the two ends of the two blocking bars are respectively fixedly connected to the two side walls of the pulverizing protective shell.

[0012] In one embodiment, multiple striking elements are mounted on the sidewalls of multiple first crushing blades or multiple second crushing blades. Each striking element includes a flexible bending rod and a wear-resistant actuating striking rod. One end of the bending rod is fixedly connected to the sidewall of the first or second crushing blade, and the middle part of the actuating striking rod is fixedly connected to the other end of the bending rod. The width of the first or second crushing blade is greater than the width of the actuating striking rod.

[0013] In one embodiment, the upper end of the belt is wound around the middle of the fixed ring. The screening component includes a rotating rod, a drive wheel, and a screening fan. One end of the rotating rod is rotatably inserted into the side wall of the fixed component, and the middle part of the rotating rod is rotatably inserted through the side wall of one end of the material discharge protective shell. The drive wheel is fixedly sleeved on the middle part of the rotating rod. The middle part of the belt passes through the through groove, and the lower end of the belt is wound around the middle part of the drive wheel. The diameter of the drive wheel is smaller than the outer diameter of the fixed ring.

[0014] In one embodiment, both the screening fan and the cleaning component are located inside the discharge protective shell. The screening fan is fixedly installed at the other end of the rotating rod, and the cleaning component is rotatably locked in the middle of the rotating rod. The cleaning component includes a rotating wheel, a lever, an inverted L-shaped connecting rod, and a brush. The rotating wheel is rotatably locked in the middle of the rotating rod. The bottom of the lever is fixedly installed on the top of the rotating wheel. The upper end of the connecting rod is fixedly connected to the bottom of the rotating wheel. The brush is fixedly installed at the bottom of the lower end of the connecting rod. The top of the lower end of the connecting rod forms an arc-shaped surface. The lever has a lever groove on the side adjacent to the control box, and the lever is located below the striking component. The side wall of the collection box adjacent to the particle collection shell has a notch. The particle collection box is installed inside the particle collection shell. The cleaning component is located directly below the lever. An inclined filter plate is installed above the particle collection box, with the lower end of the filter plate inclined towards the collection box. A guide plate is installed between the particle collection box and the collection box, with the upper end of the guide plate inclined towards the discharge protective shell, and the guide plate is located below the filter plate.

[0015] This device primarily uses food-grade stainless steel and polytetrafluoroethylene (PTFE) and other corrosion-resistant, non-polluting materials for components that come into contact with the samples, preventing sample contamination or metal ion leaching from interfering with test results during the detection process. The device is equipped with an adjustable parameter control system, allowing flexible setting of parameters such as crushing speed, time, and particle size classification to meet the sample processing needs of different testing projects. It also features sample information storage and fault alarm functions, providing uniform, uncontaminated samples that meet testing standards for agricultural product component detection, and offering a reliable basis for accurately analyzing the quality and safety status of agricultural products. When screening is not required, the screening fan can be removed.

[0016] This invention incorporates multiple striking elements. During crushing, these elements on the drive assembly strike the driven rod on the driven assembly, causing soil clods and dust adhering to the driven rod and the second crushing blade to fall off, thus reducing detection errors. Simultaneously, the multiple striking elements on the driven assembly strike the rotating shaft on the drive assembly, causing soil clods and dust adhering to the rotating shaft and the first crushing blade to fall off, further reducing detection errors.

[0017] By setting up a barrier bar, when the striking component moves below the driven rod or rotating shaft, the bending rod of the striking component will abut against the barrier bar. The bending rod will bend and deform, accumulating elastic potential energy. When the bending rod and the actuating striking rod are separated from the barrier bar, the bending rod returns to its original shape, converting the elastic potential energy into kinetic energy, causing the actuating striking rod to strike and crush the protective shell. Since the crushed protective shells are connected, the soil and dust adhering to the crushed protective shells fall off, reducing detection errors.

[0018] By setting up a screening fan, the rotation of the screening fan can generate a screening airflow F1, which can blow fine sand and gravel and some crushed soil clods to the top of the filter plate. The fine sand and gravel and some crushed soil clods are filtered by the filter plate. The fine sand and gravel fall into the particle collection box, and the crushed soil clods will fall into the collection box under the guidance of the inclined angle of the filter plate. When the filter plate is blocked by crushed soil clods, the knocking rod can be turned to knock the crushing protective shell. The crushing protective shell can transmit the vibration to the filter plate through the support frame or support plate, thereby clearing the filter plate and preventing the filter plate from being blocked and unable to screen materials.

[0019] By setting up a brush, when the striking part moves below the rotating shaft, the bending rod will abut against the actuating groove of the lever. The bending rod will be pushed downward and rotated downward. The rotation of the rotating wheel will cause the connecting rod to flip upward, so that the brush can follow the connecting rod to flip upward and clean the multiple first crushing blades or multiple second crushing blades. This prevents soil and dust from adhering to the multiple first crushing blades or multiple second crushing blades, thereby weakening the sharpness of the multiple first crushing blades or multiple second crushing blades, improving the crushing effect of the multiple first crushing blades or multiple second crushing blades, and at the same time, fully collecting materials and reducing detection errors.

[0020] In this invention, the driving mechanism can activate the screening component, and the screening component can clean the driven component of the driving mechanism. The two are closely connected and work together.

[0021] This invention has a simple structure and can not only collect residual materials well and ensure the accuracy of monitoring data, but also has a better screening effect than traditional filter screening, can prevent filter clogging, and has a longer service life.

A brush 58 is fixedly mounted on the bottom of the lower end of the connecting rod 57.

[0046] In use: 1. Put the soil clods or agricultural products that have been planted into the feeding protective shell 331. The drive component 31 and the driven component 32 can crush the soil clods of agricultural products. The energy-saving rotary motor 310 of the drive mechanism 30 starts, the rotating shaft 311 rotates, and the fixed ring 312 rotates with the rotating shaft 311. After the drive component 31 rotates, it drives the driven component 32 to rotate. During crushing, the multiple striking parts 34 on the drive component 31 can strike the driven rod 320 on the driven component 32, thereby causing the soil clods and dust attached to the driven rod 320 and the second crushing blade 321 to fall off, reducing detection errors. At the same time, the multiple striking parts 34 on the driven component 32 can strike the rotating shaft 311 on the drive component 31, thereby causing the soil clods and dust attached to the rotating shaft 311 and the first crushing blade 313 to fall off, reducing detection errors.

[0047] 2. When the striking element 34 moves below the driven rod 320 or the rotating shaft 311, the bending rod 340 of the striking element 34 will abut against the blocking rod 41. The bending rod 340 will bend and deform, accumulating elastic potential energy. When the bending rod 340 and the actuating striking rod 341 disengage from the blocking rod 41, the bending rod 340 returns to its original shape, converting the elastic potential energy into kinetic energy, causing the actuating striking rod 341 to strike and crush the protective shell 330. Because the crushing protective shells 330 are connected to each other, the soil and dust adhering to the crushing protective shells 330 and 331 fall off, reducing detection errors. After the bending rod 340 and the actuating striking rod 341 disengage from the crushing protective shell 330, the bending rod 340 and the actuating striking rod 341 will continue to strike the driving assembly 31 and the driven assembly 32, thus repeating the cycle.

[0048] 3. The crushed soil clods fall between the drive assembly 31 and the driven assembly 32. When the fixed ring 312 rotates, the belt 52 rotates along with the fixed ring 312. The belt 52 drives the drive wheel 531 to rotate, and the drive wheel 531 drives the rotating rod 530 to rotate. Because the diameter of the drive wheel 531 is smaller than the outer diameter of the fixed ring 312, the screening fan 532 rotates to generate a screening airflow F1. The screening airflow F1 can blow fine sand and some of the crushed soil clods to the top of the filter plate 121. The crushed soil clods are filtered through the filter plate 121, and the fine sand and gravel fall into the particle collection box 120. The crushed soil clods will fall into the collection box 13 under the guidance of the inclined angle of the filter plate 121. When the filter plate 121 is blocked by the crushed soil clods, the striking rod 341 can be turned to strike the crushing protective shell 330. The crushing protective shell 330 can transmit the vibration to the filter plate 121 through the support frame 15 or the support plate 16, thereby clearing the filter plate 121 and preventing the filter plate 121 from being blocked and unable to screen materials.

[0049] 4. The striking element 34 on the side of the drive assembly 31 adjacent to the control box 22 is located directly above the lever 56. When the energy-saving rotary motor 310 is started, the energy-saving rotary motor 310 of the drive mechanism 30 is started, and the rotating shaft 311 rotates. When the striking element 34 moves to the bottom of the rotating shaft 311, the bending rod 340 will abut against the lever groove 560 of the lever 56. The bending rod 340 will push the lever 56 to flip downward. The rotating wheel 55 rotates, causing the connecting rod 57 to flip upward, so that the brush 58 can follow the connecting rod 57 to flip upward and clean the multiple first crushing blades 313 or multiple second crushing blades 321. This prevents soil and dust from adhering to the multiple first crushing blades 313 or multiple second crushing blades 321, thereby weakening the sharpness of the multiple first crushing blades 313 or multiple second crushing blades 321, improving the crushing effect of the multiple first crushing blades 313 or multiple second crushing blades 321, and at the same time, fully collecting materials and reducing detection errors. After the brush 58 cleans multiple first crushing blades 313 or multiple second crushing blades 321, the weight of the brush 58 and the connecting rod 57 is greater than the weight of the lever 56. When the lever 56 cannot move in a full circle, it will swing above the rotating wheel 55. When the striking piece 34 moves below the rotating shaft 311 again, the bent rod 340 will again abut against the lever groove 560 of the lever 56. The bent rod 340 will flip downward, and the connecting rod 57 will flip upward again, so that the brush 58 can follow the connecting rod 57 to flip upward and clean multiple first crushing blades 313 or multiple second crushing blades 321, and so on.

[0050] By providing multiple striking elements 34, during crushing, the multiple striking elements 34 on the drive assembly 31 can strike the driven rod 320 on the driven assembly 32, thereby causing the soil and dust attached to the driven rod 320 and the second crushing blade 321 to fall off, reducing detection errors. At the same time, the multiple striking elements 34 on the driven assembly 32 can strike the rotating shaft 311 on the drive assembly 31, thereby causing the soil and dust attached to the rotating shaft 311 and the first crushing blade 313 to fall off, reducing detection errors.

[0051] By setting the blocking bar 41, when the striking member 34 moves below the driven rod 320 or the rotating shaft 311, the bending rod 340 of the striking member 34 will abut against the blocking bar 41. The bending rod 340 will bend and deform to accumulate elastic potential energy. When the bending rod 340 and the actuating striking rod 341 are separated from the blocking bar 41, the bending rod 340 returns to its original shape, converting the elastic potential energy into kinetic energy, causing the actuating striking rod 341 to strike and crush the protective shell 330. Since the crushing protective shells 330 are connected to each other, the soil and dust adhering to the crushing protective shells 330 fall off, reducing the detection error.

[0052] By setting a screening fan 532, the rotation of the screening fan 532 can generate a screening airflow F1. The screening airflow F1 can blow fine sand and gravel and some crushed soil clods to the top of the filter plate 121. The fine sand and gravel and some crushed soil clods are filtered by the filter plate 121. The fine sand and gravel fall into the particle collection box 120. The crushed soil clods will fall into the collection box 13 under the guidance of the tilt angle of the filter plate 121. When the filter plate 121 is blocked by crushed soil clods, the striking rod 341 can be turned to strike the crushing protective shell 330. The crushing protective shell 330 can transmit the vibration to the filter plate 121 through the support frame 15 or the support plate 16, thereby clearing the filter plate 121 and preventing the filter plate 121 from being blocked and unable to screen materials.

[0053] By setting the brush 58, when the striking member 34 moves below the rotating shaft 311, the bending rod 340 will abut in the actuation groove 560 of the lever 56. The bending rod 340 will be pushed downward and rotated downward. The rotating wheel 55 rotates, causing the connecting rod 57 to rotate upward, so that the brush 58 can follow the connecting rod 57 to rotate upward and clean the multiple first crushing blades 313 or multiple second crushing blades 321. This prevents soil and dust from adhering to the multiple first crushing blades 313 or multiple second crushing blades 321, thereby weakening the sharpness of the multiple first crushing blades 313 or multiple second crushing blades 321, improving the crushing effect of the multiple first crushing blades 313 or multiple second crushing blades 321, and at the same time, fully collecting materials and reducing detection errors.

[0054] In this invention, the drive mechanism 30 can activate the screening component 50, and the screening component 50 can clean the driven component 32 of the drive component 31 of the drive mechanism 30. The two are closely connected and work together.

[0055] This invention has a simple structure and can not only collect residual materials well and ensure the accuracy of monitoring data, but also has a better screening effect than traditional filter screening, can prevent filter clogging, and has a longer service life.

[0056] All possible combinations of the various technical features in the above embodiments are described; however, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
